Answer:

A= 4

Step-by-step explanation:

3(1-9a)+22a=2(2a-9)-15

3-27a+22a=2(2a-9)-15

3-5a=2(2a-9)-15

3-5a=4a-33

3-5a-3=4a-33-3

-5a=4a-36

-5a-4a=4a-36-4a

-9a=-36

-9a/-9 = -36/-9

A=4

The number of citizens in a town is growing according to a linear growth model. The initial population in week 0 was P_0=124 and
il63 [147K]
184 - 124 = 60
so it has grown  by 60 in 18 months. That is 3 1/3 per month.

so Number of citizens depending on month  is 124 + (1 1/3)n
or 124 + 4n/3:

At population 1000:-
124 + 4n/3  = 1000
4n/3 = 1000-124

n  =  (1000-124) * 3/4  =  657 months
